SU45496A1 - Automatic membrane level regulator in the tank - Google Patents

Description

. The invention relates to known automatic membrane fluid level regulators in tanks controlled by floats, one of which controls an auxiliary valve to communicate with or dissociate from the atmosphere of the supermembrane space, and the second controls a stop mechanism to keep the first main float in a raised state.

In the proposed automatic membrane space regulator, on both sides of the membrane are communicated with each other through an opening in the membrane, which makes it possible to use liquid filling the reservoir as a medium driving the regulator. The action of the regulator during operation is very elastic, without hydraulic shocks, which is favorably reflected both on the water conduit and on the machines of the tank supply system.

In FIG. 1 shows a vertical section through an automatic membrane level regulator in a tank; FIG. 2 is a partial view from above.

The automatic membrane level regulator in the tank is mounted inside the latter in the discharge pipe.

When the tank is filled with liquid, such as water, the latter (188) - the V-tank fills up and raises the float 46, which, moving up, moves along the axis 49. When it reaches the float 36, from now on both floats will move with water up. The large float 36, with its lever 30, lifts the auxiliary valve 27, which pushes into its seat and thereby closes the passage in the tube 20, which communicates with the supermembrane space. At this time, the tooth 4J of the locking mechanism rises to the position shown in FIG. 1, the lower tooth 42, pressed by the spring 43, will close the lock. The water supplied by the pressure water supply; into the case A, it fills the last one; at the same time, the water enters chamber B through the small opening in the diaphragm 9, the hole in the diaphragm 9 has a diameter of approximately 2 mm and is not shown in the drawing. Water fills chamber B, increasing the pressure in it. When the moment comes when the pressure in both chambers A B compares, the valve / / its weight will drop slowly onto the saddle and close the water access to the reservoir; This moment is depicted in FIG. 1. All valves and support mechanism are closed, the floats are in the upper position at limit limiter 57. From the moment the valves are closed in the pressure pipe J6, the pressure will increase, affecting the pump switch, which will block steam access to the pump and the last

In this case, the units of the steam installation are taken to measure the operation of the instruments and the entire pneumatic station.

After a certain period of time, as the water in the tank flows, the water level will begin to fall and the float 46 will lower. The float 36 and the entire system of the device are in the closed position (Fig. 1). The moment will come when the float 46, reaching the limiter 47, will press on it with its weight; the latter through the axis 49 acts on the lever 45; the end 48 of the lever is lowered, the tooth rod 42 is carried along, the latter, moving back to the right, will release the tooth 41, and the locking mechanism will open. Opened, the locking mechanism will allow the float 55 to be lowered; the latter, lowering through the lever connection, will open the auxiliary valve 27, which allows the water in chamber D to escape through the tube 20 and the opening 52; This will eliminate the pressure in chamber B above diaphragm 9. The water pressure in chamber A will increase diaphragm 9 and the rod 10 connected to it with valve 17 of chamber A mounted on it. After opening valve 17, water from chamber A will go to the tank, pressure in the discharge pipe 16 is reduced, and the pressure on the pump switch is unloaded, the latter will open the steam passage

to the pump and the pump will start working. NySh will work until the tank is filled. When the reservoir is filled with water, the regulator will come to the closing position, close and act on the locking mechanism, stop itself, etc. Thus, the ria of the pine station automatically works with the steam units.

The described automatic diaphragm sdkost level regulator in the tank with some constructive additions will control, with the help of the power of the discharge pipeline, the pump station with any kind of engines.

The subject matter of the invention.

An automatic membrane level regulator in the tank, controlled by floats, one of which controls an auxiliary valve for; communicating or separating with the atmosphere of the supramembrane space, and the second controls a stopper mechanism for keeping the first main float in a raised state, characterized in that, in order to use the liquid filling the reservoir as a medium driving the regulator, Both sides of the membrane are interconnected through the hole in the membrane.
